Understanding What Vivitrol Is and How It Works: The Science Behind Vivitrol

What is Vivitrol at its core? Vivitrol is the brand name for an extended-release, injectable form of naltrexone. This opioid antagonist (receptor blocker) fundamentally changes how your brain responds to both alcohol and opioids. When you receive Vivitrol, tiny microspheres containing naltrexone are injected into your muscle tissue, where they slowly release the medication over 28 days. This extended-release formulation means you don’t have to think about taking a pill every single day when you’re already dealing with the challenges of early recovery.
The medication works by occupying opioid and endorphin (the body’s natural opioids) receptor sites in your brain without activating them. Think of it like someone sitting in a chair at a concert but not enjoying the music. The receptors are blocked, so even if opioids or alcohol enter your system, they can’t create the euphoric high you once experienced. According to research published by the Substance Abuse and Mental Health Services Administration (SAMHSA), medication-assisted treatment (MAT) significantly improves retention in treatment programs compared to counseling alone.
How Does Vivitrol Work in Your Body?
Understanding how Vivitrol works requires looking at your brain’s reward system. When someone with alcohol use disorder drinks or someone with opioid use disorder takes opioids, the substances produced when your body metabolizes them bind to opioid receptors and flood the brain with feel-good chemicals like dopamine. This creates the pleasurable feelings that, while effective in the moment, drive continued use and make quitting so difficult. Extended-release naltrexone (Vivitrol) has been shown in one study to increase significantly drug abstinence in criminal justice offenders, with those surveyed having a confirmed opioid abstinence rate of 90% in 24 weeks, compared to a control group with only 35%.
If you’re in recovery from opioid dependence and accidentally or intentionally take opioid medicine, opioid street drugs, or any opioid containing medicines, you won’t feel the expected effects with Vivitrol. This blocking effect removes much of the motivation to use because you know the drugs simply won’t work. Second, for those battling alcohol dependence, naltrexone blocks the endorphin release that typically follows from drinking alcohol, making the experience less rewarding and helping reduce cravings over time.
Who Can Benefit from Vivitrol Treatment?
Vivitrol treatment for substance use disorder is primarily used for helping two groups: those with alcohol dependence and those with opioid dependence. Vivitrol was first approved for alcohol dependence treatment in 2006 by the Federal Drug Administration (FDA) and was later approved in 2010 for helping prevent opioid dependent relapse.
Alcohol Dependence Treatment
If you’re struggling to quit drinking alcohol despite adverse consequences in your life, Vivitrol might be the tool you need. It is FDA-approved for treating alcohol use disorder in adults who can abstain from drinking in an outpatient setting. You also don’t need to be at rock bottom to benefit from this treatment. Many people start Vivitrol after completing an alcohol withdrawal program or detox, using it to prevent relapse during those critical early months of recovery.
Opioid Dependence Recovery
For those battling opioid dependence, whether from prescription pain medications or opioid street drugs like heroin, Vivitrol offers a path forward without the risk of physical dependence that comes with other medications like methadone or buprenorphine.
However, there’s an essential requirement before you can receive Vivitrol for opioid use disorder. You must complete opioid detoxification and remain completely opioid free for at least 7 to 14 days. This waiting period is necessary because starting Vivitrol while opioids are still in your system can trigger sudden opioid withdrawal symptoms, including:
- Vomiting
- Diarrhea
- Stomach cramps
- Anxiety
- Sleeplessness
- Yawning
- Fever
- Painful joints
- Muscle cramps
The Vivitrol Treatment Process in Idaho: Finding Healthcare Providers in Idaho
Idaho has expanded access to medication-assisted treatment in recent years, with healthcare providers across the state now offering Vivitrol. At Raise the Bottom, we offer three of the few certified treatment facilities that offer medication-assisted treatment (MAT) for opioid treatment in Boise, Nampa, and Pocatello.
Rural areas of Idaho can access Vivitrol through community health centers, substance abuse treatment facilities, and some primary care offices that have joined the effort to combat the opioid crisis.
When searching for a healthcare provider, look for someone who offers evidence-based, comprehensive services beyond just the monthly injection. The most effective treatment programs combine Vivitrol with individual counseling, group therapy, and ongoing monitoring. Many Idaho providers work with addiction specialists, mental health counselors, and peer support coordinators to create a complete recovery plan tailored to your specific situation and challenges.
Initial Assessment and Starting Vivitrol
Before starting Vivitrol treatment, your healthcare professional will conduct a thorough evaluation. This includes reviewing your substance use history, performing a physical examination, and running blood tests to check your liver function. Because naltrexone can affect the liver, it’s essential to establish baseline liver function tests. Your provider will also review all other medicines you’re taking to check whether Vivitrol interacts with any of them.
The assessment process helps determine if you’re medically suitable for Vivitrol and mentally prepared for the commitment. Your healthcare provider needs to confirm you’ve completed detoxification and haven’t used opioids recently. Some offices use urine tests to verify you’re opioid free before administering the first dose.
Receiving Your Monthly Injection
Each Vivitrol dose is administered as an intramuscular injection into your buttock muscle, alternating sides each month. The injection site may feel sore for a few days, which is normal. Common injection site reactions include:
- Pain
- Tenderness
- Swelling
- A small lump where the needle entered
These symptoms typically resolve within a week and can be managed with over-the-counter pain relievers and ice packs. You’ll return to your healthcare provider’s office every 28 days (once every 4 weeks) to receive Vivitrol.
Coverage and Costs in Idaho: Understanding Vivitrol Cost with Insurance
The price of Vivitrol treatment varies significantly depending on your insurance coverage. Without insurance, each monthly injection can cost between $1,000 and $2,500, making it prohibitively expensive for many people. However, with insurance, your out-of-pocket expenses will likely be much lower, as little as $0 per visit.
Idaho Medicaid has expanded coverage for medication-assisted treatment (MAT) for substance abuse disorder under the full continuum of care in recent years, recognizing that investing in effective addiction treatment saves money in the long run by reducing emergency room visits, hospitalizations, and incarceration costs. If you have private insurance, check your plan’s prescription drug formulary or call to understand your specific coverage for Vivitrol.
Understanding Common Side Effects of Vivitrol and Safety Concerns

Like all medications, Vivitrol can cause side effects, though not everyone experiences them. The most frequently reported issues are injection site reactions, which occur in about 70% of alcohol dependence patients on average and about 5% of opioid dependence patients, but it is usually mild. Beyond the injection site, typical side effects include nausea, headache, fatigue, and dizziness. Some people report trouble sleeping, anxiety, or cold symptoms like a stuffy nose and sneezing during the first few months of treatment.
Digestive issues such as vomiting, diarrhea, stomach cramps, and decreased appetite affect some patients but typically improve as your body adjusts to the medication. Most side effects of Vivitrol are manageable and don’t require stopping treatment.
| Side Effect Category | Symptoms | Frequency |
|---|---|---|
| Injection Site | Pain, tenderness, swelling, and hardness | Very Common (5% to 69%) |
| Gastrointestinal | Nausea, vomiting, stomach pain, diarrhea | Common (11-33%) |
| Neurological | Headache, dizziness, fatigue, insomnia | Common (4-25%) |
| Serious Reactions | Liver damage, severe allergic reaction, depression | Rare (Less than 1%) |
Serious Reactions Requiring Immediate Attention
While rare, certain serious reactions need immediate medical evaluation. Watch for signs of liver damage, including unusual tiredness, yellowing of your skin or eyes, dark urine, or pain in your upper right abdomen. Your healthcare provider will monitor your liver function through blood tests, but you should report the following symptoms immediately if they develop between appointments.
- Trouble breathing,
- Wheezing
- Chest pain
- Severe skin rash
- Swelling of the face or throat
- Feeling like you might pass out
Another rare but serious condition is eosinophilic pneumonia (lung disease), which causes shallow breathing, cough, and chest pain. If you experience any of these severe reactions, seek emergency medical care right away rather than waiting for your next scheduled appointment.
Important Drug Interactions and Precautions
One of the most critical things to understand about Vivitrol is how it affects your ability to receive pain relief. Because the medication blocks opioid receptors, standard opioid pain medications won’t work if you need them for a medical procedure or serious injury. You must inform every healthcare professional treating you, including dentists and emergency room doctors, that you’re taking Vivitrol. In emergency situations requiring pain management, medical staff can use higher doses of opioids or alternative pain control methods.
Before you receive Vivitrol, tell your healthcare provider about other drugs and supplements you take. While Vivitrol has fewer drug interactions than many medications, it’s important to avoid taking opioids or any opioid medicine for at least 7 days before your injection and throughout your treatment. Using opioids while on Vivitrol can lead to opioid overdose if you try to overcome the blocking effect by taking large amounts, or it may cause no effect at all, leading to frustration and wasted resources.
Vivitrol FAQs
How long does it take for Vivitrol to start working after injection?
Vivitrol begins blocking opioid receptors within a few hours of your injection, reaching maximum effect within the first day. The medication maintains therapeutic levels in your bloodstream for approximately 28 days. However, you may not immediately notice reduced cravings, as psychological aspects of addiction take longer to address.
Can I drink alcohol while taking Vivitrol for opioid dependence?
While Vivitrol doesn’t cause a dangerous reaction if you drink alcohol like some medications do, drinking while in treatment for opioid use disorder is strongly discouraged. Alcohol lowers inhibitions and impairs judgment, which could lead to relapse on opioids. Additionally, alcohol itself is a substance of abuse that can derail your recovery.
What happens if I need surgery while taking Vivitrol treatment?
If you require surgery or dental work, inform your healthcare professional that you’re receiving Vivitrol. Standard opioid pain medications won’t provide adequate pain relief because naltrexone blocks opioid receptors. Your medical team can use alternative pain management strategies, including higher opioid doses administered in a controlled setting, regional anesthesia, or non-opioid pain medications.
Will Vivitrol show up on drug tests for employment?
Vivitrol contains naltrexone, which is not tested for in standard employment drug screenings. Urine tests typically screen for opioids, marijuana, cocaine, amphetamines, and sometimes other substances, but not for naltrexone. However, some specialized tests can detect naltrexone if specifically requested.
Who should not take Vivitrol?
Vivitrol should not be taken by people currently using opioids or in acute opioid withdrawal, those with opioid dependence, anyone allergic to naltrexone or its ingredients, or patients with acute hepatitis or liver failure. It’s also contraindicated for those who need opioid pain medications, as it blocks opioid effects.
What is Vivitrol used for?
Vivitrol is an extended-release injectable medication containing naltrexone used to treat two conditions: alcohol dependence and opioid dependence. It helps prevent relapse in adults who have stopped drinking alcohol or using opioids. Administered as a monthly injection, it works by blocking opioid receptors in the brain, reducing cravings and the rewarding effects of alcohol and opioids.
What to Remember About Vivitrol Treatment
Understanding what Vivitrol is and how this medication works represents an important step toward reclaiming your life from alcohol dependence or opioid dependence. Vivitrol offers a scientifically proven approach to preventing relapse by blocking opioid receptors and reducing the rewarding effects of substances that have controlled your life. While the medication isn’t a magic solution that eliminates all challenges on its own, it creates space where healing can happen by removing the physical drive to use substances.
